What tree frog species live in Maine?
Maine is home to two main tree frog species: the gray tree frog (Hyla versicolor) and the spring peeper (Pseudacris crucifer). The gray tree frog is larger, reaching up to 2 inches, with warty skin that can change from gray to green. The spring peeper is smaller, about 1 inch, with smooth skin and a characteristic dark X on its back. A third species, the boreal chorus frog, is less common and found in northern parts of the state.

In Maine, tree frogs sightings usually improve when you slow down and match your first stop to the most useful ID markers and likely lookalikes. Use thestate wildlife huband theroute guideto narrow your first area, then check access, weather, and distance before you settle in. A short walk with one clear viewing plan often beats covering too much ground, especially when habitat changes fast from open edges to brush, wetlands, timber, shoreline, or neighborhood cover.
How can you tell a gray tree frog from a spring peeper?
The easiest way to separate these two is by size and markings. Gray tree frogs have large toe pads and bright orange or yellow on their inner thighs, visible when they jump. Spring peepers have smaller toe pads and a dark X-shaped cross on their back, along with a dark stripe through the eye. Their calls also differ: gray tree frogs produce a slow, musical trill, while spring peepers make a high-pitched peep. Check theMaine wildlife pagefor more species comparisons.
Where in Maine should you look for tree frogs?
Tree frogs are most often found in southern and central Maine, particularly near ponds, marshes, and slow-moving streams with plentiful vegetation. Look in cattail marshes, woodland pools, and along the edges of lakes. Acadia National Park and the Kennebec River valley are reliable spots. Start with small ponds near your location, especially after a warm rain. For best odds, visit during the breeding season.

When is the best time to spot tree frogs in Maine?
The prime window is late April through early July, with peak activity in May and June. Tree frogs are nocturnal and most visible after dusk, especially following a rainfall when humidity is high. During breeding season, males call from vegetation near water, making them easier to locate. Daytime sightings are rare but possible on overcast days. Focus your efforts on warm, damp evenings.
